Summary of the article:

The main idea of the article is that how the banana peels can help to remove heavy metals from polluted water. The sciences that are being used is that researchers had found many compounds inside the banana peel like carboxylic acid, and the acids that bind to many metals came to contact. When carboxylic acid bond with a reactive metals, it creates hydrogen and a salt that are not poisonous. Bond is when two chemicals stuck together and chemically reacted.

I think this will be very useful for polishing stuffs instead of water because recently water cost a lot to use it so that it also saves money a lot. Also we don’t have to use the banana peel a lot. We can use it 11 times!! However, there is 1 bad point of banana peel. It’s that it can’t kill bacteria.

So what is stereotypes? It’s kind of label, usually led by appearance, nationality and culture. For example Japanese people do karate or kendo, and often eat sashimi and sushis. I think this is stereotypical because I’m Japanese and some of my friends do kendo and love eating sushis. But in someways stereotypes are useful. If you have meetings or have a lunch or a dinner with European people in Japan, you might go to Japanese restaurant so that they can taste Japanese food and Japanese culture. However, stereotypes might be bad because people might insult other people by religion, culture, skin colour, and books. I think this will cause power struggle. So we must not insult people by their own stereotypes.
